What does it do in the case of a leak (and similar "historical"
analysis)?

The point of the leak is not the point of detection, but it's the
_former_ which is interesting.  As recording the entire state of a
program for every allocation is probably too expensive for any
non-trivial program, it doesn't seem there's much the debugger can do
other than act as a convenient "show me this source file location"
tool....
